Added a logic to track if a scan happend based in the resolver position and...

Fixed array readings.

Fixed the retrieve of 16 bits values. The ipbus protocol is based on word (32bits) but we need to save 16 bits scan data in some register. Therefore, the first 16 bits stores one point and the other 16 another point of a scan data. We were throwing half of the data away before, now it is right.

Now there is a mechanism to detect whenever a scan has happened based on the resolver position and trigger the scan data reading right after it.

Some cleanup stuff left from the last MR.
